AbstractAbstract
[en] The paper presents a general concept of a hybrid propulsion system, based on an SI internal combustion engine fueled by methanol dissociation products (MDP). The proposed hybrid propulsion scheme is a series hybrid, which allows the engine to be operated in an on-off mode at constant optimal regime. The engine is fed by gaseous products of methanol dissociation (mainly hydrogen and carbon monoxide) emerging from an on-board catalytic reformer. The general scheme and base operation features of the propulsion system are described. The benefits that may be achieved by combining the well-known idea of on-board methanol dissociation with the hybrid vehicle concept are discussed. The proposed scheme is compared with those of systems operating on gasoline, liquid methanol, hydrogen and also with the multi-regime (not hybrid) engine fed by MDP

AbstractAbstract
[en] Corn, wheat, sugar cane.. The multiplication of biofuel refineries has led to a rise of the prices of agriculture products. The question is: do we need ethanol? The US situation gives an answer: the offer exceeds the demand and ethanol prices have dropped down. Other environmental and socio-economical consequences of biofuels development are put forward by the UNO, the IMF and by non-governmental organizations who foresee a dramatic rise of food products prices and an aggravation of starvation in developing countries.

AbstractAbstract
[en] For the purpose of a direct methanol fuel cell (DMFC), this research investigates the kinetics of methanol oxidation in a porous layer consisting of external hierarchical nanostructures through 2D COMSOL simulation. Three different lengths of nanowires (L) were considered in simulations. The investigation showed that specific activity was reversely proportional to nanowires length and roughness factor (Rf). However, the current density increased by increasing Rf. Although the current density in case of L = 200 nm and 500 nm was identical with respect to Rf, there was a slight deviation when L = 1000 nm due to the changing from kinetic to diffusion controlled regime, which was identified by investigation of Thiele modulus. The catalytic efficiency for L = 1000 nm dropped to 50% at Rf = 140, whereas the high efficiency with no mass-transport limitation was achieved by shorter nanowires. Therefore, increasing Rf within the simulation range resulted in increasing the total catalytic activity but simultaneously decreasing the specific activity because of the decrease in pore accessibility and catalytic efficiency of nanostructures.

AbstractAbstract
[en] Signed by more than 25 associations, or enterprises and the Government, this charter underlines eight main points in favor of the super-ethanol E85 development. Then the charter defines the actions plan allowing to assure the success of the launching and the development of the super-ethanol E85 channel: the necessary standards and technic, the diversified and impressive offer of flex-fuel vehicles, the E85 distribution network on the territory, the development of a competitive and sustainable channel of ethanol production, the economic and fiscal conditions allowing the E85 to be competitive facing the fossil fuels and the following of the actions plan.

AbstractAbstract
[en] Life-cycle assessment is a technique that allows consideration of key environmental impacts for the entire life cycle of alternative products and processes in order to select the most appropriate alternative. Ethanol, used as a fuel additive or as a neat fuel, is an alternative to conventional gasoline. To properly compare gasoline with ethanol fuel, a life cycle analysis for both energy systems must be completed. It is also necessary to consider the various available sources of feedstock for producing ethanol as well as the technologies used to convert feedstocks to ethanol. This paper compares the environmental effects of producing ethanol in Canada from corn, wheat, and poplar trees. Results show that in the life-cycle of producing 1000 litres of ethanol and 3592 kWh of electricity, biomass feedstock production contribute less than 10 per cent of air emissions for systems considered. It was also shown that ethanol production systems utilizing cogeneration to offset average grid electricity tend to have significantly lower overall emissions than non-cogeneration systems. Offset savings could be further reduced if it was assumed that gas-fired, or hydro was being offset instead of grid-average (i. coal-fired) power. 19 refs., 10 tabs., 11 figs

AbstractAbstract
[en] The biofuels are presented as a solution to the greenhouse gases and the petroleum consumption decrease. The development of the biofuels needs an active research of the production, transformation and use costs improvement. It will be necessary to prepare the market of the biofuels to the globalization. Some recommendations are also provided in the domains of the vegetal oil ester, the ethanol for the diesel and for the development of simulation tools to evaluate the costs. (A.L.B.)
